Compensating for Directional Coupler Response

If you use a directional coupler to sample power in your measurement configuration, you should enter the
coupled arm power loss value into the power loss table, using the following procedure. You can enter the
loss information in a single segment, and the analyzer will assume that the value applies to the entire
frequency range of the instrument. Or, you can input actual measured power loss values at several
frequencies using up to 12 segments, enhancing power accuracy.
1. Press

The analyzer shows the notation EMPTY, if you have not entered any segment information.
2. To create the first segment, press

3. Press and enter the power loss that corresponds to the attenuation of the directional coupler
LOSS
(or power splitter) at the frequency that you have entered in the previous step. Complete the power loss
entry by pressing

NOTE Remember to subtract the through arm loss from the coupler arm loss before entering it into
the power loss table, to ensure the correct power at the output of the coupler.
